Only minor stuff and it may be the angle of the film but it looks like you skip to perform a lead low kick, when I used to fight I always personally found it better to just drop in to the lead low kick as opposed to skip, your way isn't wrong or anything but I just found it was harder for the opponent to block as it was a bit quicker without the skip. The only time I would usually vary it was if I used a front kick with the rear leg in which case I would use a springing low kick.

Also hands look like they are dropping sometimes during combinations a little bit.

i usually do 10x2 minute rounds per morning. nice way to wake up. im southpaw cos the good lord hates me and decided i was destined to rot in hell, or thats what my coaches tell me.

my hands do look kinda low. i think i have a bad habit of dropping my left slightly when i move out. ill add it on to cutting an angle afterwards. i also seem to punch down at a fair angle, but i do spend a lot of time fighting midgets.
